Building on OpenAI as a long term business strategy is dubious. Better go with an established cloud player for these solutions imo.

OpenAI might burn through all their money, and end up dropping support for these features and/or being sold off for parts altogether.

I doubt that there is any risk at all. One is that this is probably a minor aspect of the business seeing these AIs. AIs that ive seen deployed so far for real work seem to best be done in side business offerings that you can tolerate a high false positive / false negative rate, but also isnt price sensitive enough that building a fully done automated pipeline classically is worth it or possible.
